HOSE-CLAMP.

SPECIFICATION forming part of Letters Patent No. 341,365, dated May 4,1886.

Application filed February 11, 1585.

To all whom it may concern.-

Be it known that I, VILLIAM J. WILSON, of Pittsburg, in the county ofAllegheny and State of Pennsylvania, have invented a new and usefulImprovement in Hose-Clamps; and I do hereby declare the following to bea full, clear, and exact description thereof.

In the use of water-hose at fires much valuable time is lost andfrequently great danger is incurred by the bursting of a section ofhose. In such case it is usually necessary to shut off the water at theplug or other source of supply in order to be able to remove the damagedsection, and as such source is often a considerable distance away muchtime is necessarily lost in effecting the change. As this loss of timeoccurs at a critical moment it often results in great damage toproperty, and sometimes in loss of life. It is not an unusual occurrencethat a burst occurs in a section forming part of a line running up ahigh building, and when this happens the change involves more time andtrouble than when the accident occurs on the ground.

My invention consists in an improved clam ping and holding deviceadapted for use with different sizes of hose, by which the water may beshut off back of the damaged section and held closed until such sectionis replaced by another section, and also by which the line can be heldon a building or ladder while the change is being made.

To enable others skilled in the art to make and use my invention, I willnow describe it by reference to the accompanying drawings, in whichFigures 1 and-2 are side views illustrating the construction andoperation of one form of my improvement. Fig. 3 is a detail ofconstruction. Figs. 4 and 5 are views of modifications.

Like letters of reference indicate like parts in each.

In Figs. 1 and 2, a and 1) indicate two jaws or bars, which are hingedtogether at c. On the outer'end of the jaw a is a hinged hook or link,(I, which is designed, when the jaws are brought together, to engagewith the hook e on the end of thelever f. Thelever f is'hinged to theouter end of the jaw I) at b, and at its rear end is provided with ahinged ring or hook, g, which, when the jaws are tightly Serial No.155,561. (No model.)

closed on a section of hose, as shown in Fig. 2, is intended to hookover the pin 1) on the rear end of the jaw b, so as to hold thejaws in aclosed position.

The operation of my improvement is as follows: If a section of hose inuse in a line should burst, the jaws a b are placed, as shown in Fig. 1,around the next section back, alittle in the rear of the coupling,between the two sections, and pressed together until the hook 6 can beengaged with the link (I. Then force is applied to the lever f and it ispressed down, the link (I, supported on the jaw a, serving as a fulcrumuntil the sides of the hose 71 are tightly compressed together and thewater is shut off. It may be secured in this position by putting thering 9 over the pin b as shown in Fig. 2.

In the modification shown in Fig. 4 the ends of the jaws a Z) areextended considerably to form handles on, and the securing-ring g isplaced on the outer end ofjaw a. and turns up over the end of the jaw b,which may be provided with a notch, I), to receive it. In this instancethe lever f has its fulcrum in a link or strap, '5, depending from eachside, and taking over pins k, one on each side. The links a are guidedby oblong staples Z, one on each side of thejaw I).

In using this device the hose extends between the jaws, back of the pinsIt. The jaws are closed on it by using their outer ends, m, as handlesuntil the eyes or hooks of thelinks i can be put over the pins 7;, andthen the pressure of the lever f is applied, the link 2' serving as afulcrum, which is supported by the lowerjaw, a, as in the case of thelink (I in Fig. 1. The extension of the jaws beyond the end of the leverf, forming handles m, affords a means of applying pressure on the hosein addition to the lever.

In Fig. 5 theleverf is dispensed with, and the pressure is appliedsolely by means of the handles m. This form is useful with light hoseand a light pressure of water, but has not nearly the power of the otherforms, and therefore is not applicable to large stiff hose and a heavywater-pressure.

The form shown in Figs. 1 and 2 is more portable, and it can be foldedup into a smaller compass, and may be carried in the pocket.

In Fig. 3 I show how the jaws are adjusted at the hinge to receivevarious sizes of hose. Here the screws which secure the jaw b to thehinge-plate 0 pass through slots 0, and a setscrew, 01, works throughthe upper angle, a, of the plate against the end of the j aw, so that byscrewing the set-screw in or out thejaws may spread the desired distanceapart at the hinged end.

By the use of this simple and effective device, thehinge being adjustedto suit the diameter of the hose, the water may be shut off at anydesired point in a line of hose without trouble or loss of time, so thateffective service may be rendered in moments of emergency, when the lossof a few moments may be fatal to life and property.
